The optimal adjuvant treatment of high-risk low-grade glioma (LGG) is controversial. We performed this retrospective cohort study to compare three treatments including observation, radiotherapy (RT) alone, and radiotherapy combined with concomitant and adjuvant temozolomide (TMZ) chemotherapy (STUPP regimen) in patients with high-risk LGG. Patients with high-risk (age > 40 or undergoing subtotal resection or biopsy) LGG treated with observation or radiotherapy alone or STUPP regimen after operation were retrospectively analyzed. Survival rates were evaluated by the Kaplan-Meier method; the log-rank test was applied to compare differences between groups. A total of 250 patients met the inclusion criteria. Median follow-up for living people was 70 months. Overall, patients who received radiotherapy with or without temozolomide had better progression-free survival (PFS) and overall survival (OS) when compared with observation (median PFS: observation, 59 months; RT, 82 months; STUPP, not reached; median OS: observation, 96 months; RT, not reached; STUPP, not reached), whereas STUPP regimen did not further prolong PFS or OS than RT alone (PFS, P = 0.203; OS, P = 0.146). In oligodendroglioma (IDH mutant and 1p/19q codeleted) subtype, only STUPP regimen brought longer PFS when compared with observation (P = 0.008). The incidence of grade 3 or 4 neutropenia (P < 0.001) and nausea or vomiting (P = 0.004) was higher in the STUPP group than the figure for the RT alone group. PFS and OS were similarly improved in patients with high-risk LGG receiving RT alone or STUPP regimen. However, only STUPP regimen was able to bring better PFS for oligodendroglioma (IDH mutant and 1p/19q codeleted) subgroup. Longer follow-up time is needed to determine an association with treatment effect in different histological and molecular subgroups.
BackgroundIn the first year of dialysis, patients are vulnerable to cardiovascular disease (CVD) hospitalization, but knowledge regarding the risk factors and long-term outcomes of cardiovascular readmission within the first year after dialysis in incident continuous ambulatory peritoneal dialysis (CAPD) patients is limited.MethodsThis retrospective cohort study was conducted in incident CAPD patients. The demographic characteristics, laboratory parameters, and CVD readmission were collected and analyzed. The primary outcome was all-cause mortality, and the secondary outcomes included CVD mortality, infection-related mortality and technique failure. A logistic regression was used to identify the risk factors associated with CVD readmission within the first year after dialysis. Cox proportional hazards models were used to evaluate the association between CVD readmission and the outcomes.ResultsIn total, 1589 peritoneal dialysis (PD) patients were included in this study, of whom 120 (7.6%) patients had at least one episode of CVD readmission within the first year after dialysis initiation. Advanced age, CVD history, and a lower level of serum albumin were independently associated with CVD readmission. CVD readmission within the first year after dialysis was significantly associated with all-cause (HR 2.66, 95%CI 1.91–3.70, p < 0.001) and CVD (HR 3.42, 95%CI 2.20–5.31, p < 0.001) mortality, but not infection-related mortality or technique failure, after adjusting for confounders.ConclusionsOur findings suggest that an advanced age, a history of CVD, and a lower level of serum albumin were independently associated with CVD readmission. Moreover, CVD readmission was associated with all-cause and cardiovascular mortality in incident CAPD patients. 相似文献
